PLEASE HELP!! AR stands for Radio Detection And Ranging. How does this technology work?

1: Radio waves are sent by a transmitter and the receiver picks them up at location down-range.

2: Radio waves are sent by a transmitter and reflect back to a receiver when they run into an object.

tbh i dont know ether

d. learned preferences i believe is your answer

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
